为预备可再生能源发电中出现的发电量波动，我们需要储备过剩的电能以保证多云、无风的午后和夜晚的用电。

To prepare for the power fluctuations endemic to renewable energy, we'll need to inventory excess power to use during cloudy, windless afternoons and nights.

提出了发电系统停运容量预备表的概念，并据此给出了先形成发电系统停运容量预备表，再建立发电系统停运容量模型的实用算法。

A new concept, the generation system outage capacity probationary model, is presented. Based on this concept, a practical algorithm for building generation system outage capacity model is proposed.
